This image taken between 1920-1930 depicts open-cut hydraulic sluicing at the Three Mile Mine, located about five kilometres south of Beechworth. Alluvial, or surface, mining began on this site in the 1850s, but was soon replaced by hydraulic sluicing methods. By the start of 1880 it is estimated that nine hundred miles of water races had been cut though soil and rock in the Beechworth district. Hydraulic sluicing employs high pressure jets of water to blast away large areas of earth and wash it down to be run through a sluice box. Gold gets caught in the sluice and the remaining slurry is washed away. Large water quantities were required for hydraulic sluicing, and the long water races and deep tailraces that were constructed were considered great engineering feats. This method of mining is extremely effective, but causes significant environmental damage and impacts to waterways and agricultural operations. Miners at Beechworth built extensive networks of races and dams to secure reliable supplies of water on a scale far greater than elsewhere in Victoria. By the 1880s Beechworth's water barons continued to hold more than half of all the water right licences on issue and undertook sluicing operations on a massive scale. The manipulation of surface and ground water via race networks was well planned and recorded in detail by local mining surveyors. The maps that were created, combined with modern geo-spatial technologies, provide a vital key in understanding the great lengths to which miners went to capture and control critical water resources. Today, Three Mile mine is called Baarmutha. The Three Mile Mine was unproductive until 1865 when John Pund and three other miners secured a fifteen year license and constructed a water race from Upper Nine Mile Creek to Three Mile Creek. In the early twentieth century Pund & Co. averaged over one thousand ounces of gold per year from the mine. After Pund's death in 1915, GSG Amalgamated Co operated the site, continuing sluicing until 1950. This image of hydraulic sluicing methods shows the extent of water-works engineering in the landscape. This photograph has historic and research potential for understanding changes to the landscape, the evolution of mining methods, and the extensive construction, manipulation and management of water networks in the Beechworth district.

Can we humans simply ignore the fires, the floods, and the increase in deaths brought about by climate change? In this book, Australian farmers - who bear the brunt of climate change, yet accept the science - share their experiences with the unpredictable weather events, the reduction in rainfall, and the shift to hotter months which are a challenge to farming cycles. Far from contributing to the problem with their farming practices, these farmers demonstrate how to reduce their greenhouse gases - to zero or below in some cases - while remaining profitable. They are all committed to pass on their farm in a better condition than when they first purchased or inherited it. With crops or livestock, big or small, they have worked cooperatively, mostly through land management, to plant thousands of trees, which has led to the daily presence of over 100 bird species. The farmers' inspiring and informative stories will open up a new world to most urban dwellers. A summary of climate change impacts - and an account of the numerous economic, political, and media barriers toward change - combine to provide a context for their work. 280 pages : colour illustrations, colour maps, colour portraits ; 23 cm.
